Thanks for your support. The game was a very early WIP. In the meantime, a lot has happened and the game is now finished. It will be released for the Amiga 40 in Germany and will be available as a collector's edition box set. I wasn't able to test it on an Amiga 4000. So far, the game has been tested on an Amiga 500 and a1200, and as you already wrote, it ran great.
